- the present invention relates to an aerosol provision system, a method of producing an aerosol from an aerosol provision system and aerosol provision means.
- Aerosol provision systems are known. Aerosol provision systems often have aerosol generating components for generating aerosols from aerosol generating material. Modern devices operate on demand as a result of a user pushing a button or inhaling on the device prior to a puff being delivered to the user. Such devices deliver energy from a power source to an aerosol generating component. This set process can be repeated to provide more aerosol to a user.
- the present invention is directed toward solving some of the above problems.
- an aerosol provision system comprising: a power source; an aerosol generating component; and, control circuitry, wherein the control circuitry is arranged to control the power source and the aerosol generating component to provide a selection between at least: a predetermined aerosolisation profile; and a variable aerosolisation period, to be applied to aerosol generating material.
- a method of producing an aerosol from an aerosol provision system comprising: providing a power source; providing an aerosol generating component; and, providing control circuitry, the control circuitry arranged to control the power source and the aerosol generating component, providing a selection between at least: a predetermined aerosolisation profile; and a variable aerosolisation period, to be applied to aerosol generating material, applying the selected one of the predetermined aerosolisation profile and the variable aerosolisation period to aerosol generating material.
- aerosol provision means comprising: power means; aerosol generating means; and, control circuitry, wherein the control circuitry is arranged to control the power means and the aerosol generating means to provide a selection between at least: a predetermined aerosolisation profile; and a variable aerosolisation period, to be applied to aerosol generating material.

- Figure 3B is a longitudinal cross-sectional view of an aerosol provision system according to an example.
- Figure 4 is a schematic flowchart for a method of producing an aerosol according to an example.
- a “non combustible” aerosol provision system is one where a constituent aerosolisable material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery to a user.
- e-cigarette or “electronic cigarette” may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol provision system / device and electronic aerosol provision system / device.
- an aerosol provision system 100 is shown.
- the aerosol provision system 100 has a power source 110.
- the aerosol provision system 100 has an aerosol generating component 120.
- the aerosol provision system 100 has control circuitry 130.
- the control circuitry 130 is arranged to control the power source 110 and the aerosol generating component 120 to provide a selection between at least a predetermined aerosolisation profile and a variable aerosolisation period to be applied to aerosol generating material.
- the power source 110 is shown connected to the aerosol generating component 120.
- the connection may be an electrical connection to allow the power source 110 to provide electrical signals to the aerosol generating component 120.
- the power source 110 may provide energy to the aerosol generating component 120 for aerosolisation of aerosol generating material.
- the power source 110 is shown connected to the control circuitry 130.
- the control circuitry 130 may control the delivery of energy from the power source 110 to the aerosol generating component 120.
- the control circuitry 130 may operate to control delivery of energy from the power source 110 to aerosol generating component 120 to provide a predetermined amount of aerosolisation from aerosol generating material.
- the power source 110 may, in an example, be a battery or the like.
- the power source 110 may contain chemical energy which can be converted and delivered as electrical energy.
- the aerosol provision system 100 has a housing 140 within which the power source 110, the aerosol generating component 120 and the control circuitry 130 are located.
- the predetermined aerosolisation profile may comprise a plurality of aerosolisation phases and a plurality of non-aerosolisation phases.
- the aerosolisation phases may be phases wherein the aerosol generating component 120 is supplied with energy from the power source 110, under control of the control circuitry 130.
- the non-aerosolisation phases may be phases wherein the aerosol generating component 120 is not supplied with energy from the power source 110.
- the predetermined aerosolisation profile may be a profile that can be selected by a user desiring the delivery of aerosol over an extended “smoking session”.
- the predetermined aerosolisation profile may therefore have a sequence of active periods and non-active periods, the timings of which may be predetermined and which may be different (or the same) for each period. This may produce aerosol for inhalation at specific timings over a given period.
- the variable aerosolisation period may be a continuous period, which can be varied in length, wherein the aerosol generating component 120 is supplied with energy from the power source 110, under control of the control circuitry 130.
- the variable aerosolisation period may be user controlled so that the user can select a relatively long, or short, period over which to produce an aerosol.
- the variable aerosolisation period therefore does not have non-aerosolisation phases alongside aerosolisation phases.
- the variable aerosolisation period is rather an on or off use-mode for the system 100.
- there is a cap on the maximum length of the variable aerosolisation period so as to prevent misuse of this setting.
- the longest single use may be capped at less than 30s or the like. This can function as a safety feature so as to protect the system 100.
- an aerosol provision system 200 is shown.
- the aerosol provision system 200 has similar features to the example of an aerosol provision system 100 shown in Figure 1. Similar features have similar numerals with the number increased by 100. These will not necessarily be discussed in detail here.
- the aerosol provision system 200 shown in the example of Figure 2 has control circuitry 230 which has an activatable element 232.
- the activatable element 232 is for controlling the power source 210 and aerosol generating material 220.
- the activatable element 232 may be a user- activatable element (such as a button or switch or the like), a user interface (such as a touch sensitive screen, graphics user interface or the like) and/or a sensor (such as a fingerprint scanner, puff detector, QR code reader, barcode reader or the like).
- the activatable element 232 may be activated once a state detection is made.
- the state detection might be, for example, that an RFID sensor has detected an RFID known to be valid (by, for example, cross-reference with a database of valid RFIDs) such that the aerosol provision system 200 is controlled to provide energy from the power source 210 to the aerosol generating component 220.
- the activatable element may therefore be user activatable or non-user activatable.
- a puff detector may allow for puff activation of the system 200.
- the puff detector may detect when the user is inhaling on the system 200 and therefore result in activation of the system 200.
- the system 200 may be activated to provide a predetermined aerosolisation profile or a variable aerosolisation period based on e.g. the length of time of inhalation or intensity of inhalation. For example, a short (less than 2 seconds) inhalation results in the system 200 providing an aerosolisation period and a long (more than 2 seconds) inhalation results in the system 200 providing a predetermined aerosolisation profile.
- the skilled person would be aware of implementations that could utilise puff activation.
- the control circuitry 230 may be configured to determine a state of the activatable element 232 and based on the state of the activatable element 232, determine whether to apply the predetermined aerosolisation profile or the variable aerosolisation period to aerosol generating material. This may be that, for example, a fingerprint scanner has detected a movement in a first direction which results in the selection, and application of, a predetermined aerosolisation profile. Alternatively, a fingerprint scanner may detect a movement in a second direction which results in the selection, and application of, a variable aerosolisation period.
- an aerosol provision system 300 is shown.
- the aerosol provision system 300 has similar features to the example of an aerosol provision system 200 shown in Figure 2. Similar features have similar numerals with the number increased by 100. These will not necessarily be discussed in detail here.
- FIG. 3A shows an aerosol provision system 300 with control circuitry 330 with an activatable element 332.
- the activatable element 332 is shown in a first state.
- the activatable element 332 is shown as a physical component, such as a button or switch or the like, however it may as easily be any of the above discussed options.
- the activatable element 332 merely needs to indicate a difference between states in which it may put, such as can be performed by a touchscreen.
- the activatable element 332 is put into a first state and signals to the control circuitry 330 that it is in the first state.
- the control circuitry 330 then controls the power source 310 to provide energy to the aerosol generating component 320 in a first manner.
- Figure 3B shows an example of an aerosol provision system 300 wherein the activatable element 332 is in a second state, which may lead to the control circuitry to control the power source 310 to provide energy to the aerosol generating component 320 in a second manner.
- the activatable element 332 is shown on the housing 340 of the aerosol provision system 300 however may be located inside the aerosol provision system 300.
- the activatable element 322 may be a user-activatable element
- the user-activatable element may be a switch that can be affected in a first way to provide a predetermined aerosolisation profile to an aerosol generating material, and the switch can be affected in a second way to provide a variable aerosolisation period to an aerosol generating material.
- the switch 332 is moved towards one end of the system housing 340 for the first way and towards the other end of the system housing 340 for the second way.
- Another example may be a push button which is depressed slightly for a first way and depressed more/entirely for a second way.
- the control circuitry 330 may have a database or the like for storing predetermined aerosolisation profiles.
- the control circuitry 330 may therefore provide a selection between a plurality of predetermined aerosolisation profiles and a variable aerosolisation period to be applied to an aerosol generating material. This may allow the aerosol provision system 300 to accommodate users’ preferences in aerosol.
- a first predetermined aerosolisation profile may provide an aerosol with more or less nicotine (for example) than a second predetermined aerosolisation profile.
- the user may select their preferred option of predetermined aerosolisation profile.
- the user may make their selection from the activatable element 332, such as a graphic user interface on a touchscreen on the aerosol provision system 300.
- the predetermined aerosolisation profile supplied by the control circuitry may be based on consumable recognition.
- a consumable containing a specific aerosol generating material (or combination of aerosol generating materials) may be inserted into the aerosol provision system 300 prior to use.
- the consumable may have a detectable element on it, such as a barcode, QR code or the like.
- the detectable element may be detected by the control circuitry 330 (or activatable element 332). This may allow the control circuitry 330 to provide a predetermined aerosolisation profile to the consumable based on the specific aerosol generating material or aerosol generating materials present in the consumable, as detected and recognised by the control circuitry 330.
- a suitable predetermined aerosolisation profile may be provided to any specific consumable across a range of consumables. This, in turn, provides greater flexibility of use for a user of the aerosol provision system 300.
- the predetermined aerosolisation profiles that may be provided by the control circuitry 330 may differ to one another by any suitable factor. These include the number of aerosolisation phases, the intensity of aerosolisation phases and, the frequency of aerosolisation phases.
- a predetermined aerosolisation profile for use with a consumable which has a majority aerosol generating material of menthol may have a lower intensity of aerosolisation phase (e.g. a lower operational temperature to produce an aerosol from the aerosol generating material) than a consumable which has a majority aerosol generating material of tobacco. This may be based on the operational temperatures at which a menthol consumable and a tobacco consumable generate aerosols.
- the consumable may have a plurality of different sections each of which contains one or more aerosol generating materials.
- a first section may be provided with a first predetermined aerosolisation profile, whereas a second section may be provided with a second predetermined aerosolisation profile.
- the second predetermined aerosolisation profile may differ from the first predetermined aerosolisation profile.
- the consumable has three sections.
- the first section may be heated to a low operational temperature (to release, for example, menthol).
- the second section may be heated to a high operational temperature (to release, for example, nicotine).
- the third section may be heated to a medium operational temperature (to release, for example, humectant say propylene glycol).
- a user may select which section to use and in which order to personalise the aerosol produced or their taste preference.
- the consumable may provide around 10 puffs for a user. Therefore the frequency of variation of the profile may be with each puff which may be around every 30 seconds or so , as desired by the user.
- the aerosol provision system 300 may provide a continuous aerosolisation to any consumable provided to the aerosol provision system 300 as a result of interaction with the activatable element 332 in a predetermined manner.

- the heating mechanism may be part of an inductive heater which provides for rapid heating of aerosol generating material.
- the heater may have an operational temperature of around from about 160 to about 300 °C for aerosolisation of the aerosol generating material.
